COMBINATION GAS ANCHOR AND SAND SETTLER- -WITH PER-FOETIONS.

Application filed August 18, 1924, Serial No. 732,820.

Y 10 all 107mm t may concern:

Be 1t known that I, HOWARD B. BLANTON, arcltizen of the United States,residing at yIowa Park, in the county of lVichita and State of Texas,Vhave invented certain new and useful `Improvements in CombinationGasAnchors and Sand Settlers with Perforations, of which the followingis a speciiication.

This invei'ition relatesV to pumps and refers more particularly to apump designed for the purpose of separating sand from oil in the processof pumping oil from wells.

The primary object of the invention resides in the procession of a meanswhereby sand is excluded from the oil before the latter enters throughthe valves, thereby eliminating the necessity of suspending operationsin order to clean said valves of deposits of sand.

Another object of the invention is the provision of a chamber incombination with a pump which provides a suitable receptacle for sanddrawn into the pump with the oil, and also a means provided. for theremoval of sand from said chamber.

Features of the invention are the latters simplicity, durability andapparent utility.

Other objects, features and advantages as well as those above setr forthwill be described no1-e comprehensively in the course of the followingdetailed description wherein:

Figure l represents a cross-sectional view of the invention inelevation, as it appears 1n attachment to a pump.

Figure 2 is also an elevational view of the invention, attac-hed.

Figure 3 represents an elevation view of the invention in cross-section.

Figure l is a cross-sectional view of Figures l and 2 on lines 4 4.

Following the reference characters, l denotes an oil pump of ordinaryconstruction, with the usual ball valves 2 2. Provided on the lowerportion of the pumps is a threaded collar 3. The barrel 4 constitutingthe upper portion of the invention is adapted to be engaged by thiscollar in vertical,

alinement with the pumps; and constitutes a part of the'pump assembly. y

Suitably connected to the barrel 4 by collar 5 is a chamber 5a. Thischamber is adapted to receive deposits of sand entering the chamber 5athrough the walls of barrel 4 by Way of oil Conducting means 8, whichingress of oil and sand will be later described in the operation of thepump. o

The chamber 5a is provided wit-l1 a screw cap opening 6 in its lowerportion for the removal 'of sand therefrom. e

it will be observed that thesand separating chamber 5a is so arrangedthatthe ingress of oil has a downward flow into the Isand receivingchamber flush with the walls there of in order that the sandr will havea tendcncy to settle in said chamber andwill not be incorporated withthe oil in its upward flow through the valves.

In the operation of the device; upon the upward motion of the piston la,a vacuum is created in the barrel 4 which vacuum draws the oil andpossibly a certain amount of sand into the said barrel through the parts7 7 anddownwardly through the ani guiar oil conductors 8 8, thence intothe sand receiving chamber 5a, at which time they sand is adapted tosettle therein and allow the oil to continue upwardly through the valves2 2 into the upperchambers comparatively free from grit.

It should be understood that it is advisable in constructing the member4 to have the oil conducting members 8 as nearly straight as possibleand be devoid of sharp curves and angles to eliminate friction; as thesand passing with the oil would grind at these. angles or curves, andwould weakeny the member 4:.

It is not desired that the invention be limited to the specificdisclosure as herein described and that minor changes may be resorted toas fall within the meaning and scope of what is herein claimed.

I claim:

l. In a device of the character described, the combination with a pumpcasing and a sand trapping chamber, of a separating barrel interposedbetween said casing and trapping chamber, said barrel beingsubstantially square in cross section and having a' cylindrical passageway'thereincommunicating with said pump casing and sand trappingchamber, a plurality of longitudinally extending oil conducting channelsformed in the ways of said barrel opening exteriorly of the barrel attheir upper ends and interiorly of the barrel at their lower ends, andsaid passage way reducing in diameter towards its lower end.

2. In a device of the character described,

soy

the combination With a pump casing and a sand trapping chamber, of Yaseparating barrel interposed between said easing and trapping chamber,said barrel beingsubstantially square in cross sectionandhaving acylindrical passage Way therein communicating with said pump casing andsand trapping chamber thereby forming thickened corners in the Walls ofsaid barrel, said thickened corners being` each provided With aninclined oil conducting channel, Isaid channels opening at their upperends eXteriorly of the barrel and at their lower ends interiorlythe-reof.

3. In a device of the character described, the combination with thelower valved intake end of a pump casing, of a barrel of substantiallythe same diameter as the casing` and secured to and projectinglongitudinally from the lower end of the casing', the Walls of thebarrel being provided with inclined oil conducting channels opening` attheir upper ends exteriorly of the barrel and at their lower endsinteriorly thereof, the barrel being of tapering formation from itsupper to its lower end while its inner surface is cylindrical, and theouter surface substantially rectangular in cross section with thethickened portions of the walls positioned at the corners thereof, sothat the channels may be provided through' these thickened portions andnot interfere with the passage of oil outwardly throughl the barrel, atrapping chamber detachably secured to the lower end of the barrel andin alignment therewith, and a detachable plug associated i with the`chamber for permitting off access thereto.

In testimony whereof I have signed my name to this specification.
